TIRE-PLUG.

Specification of Letters Patent.

Patented Dec. 12, 1905.

Application filed February 27,1901. Serial No- 49,151.

To all whom it may concern:

Be it known that I, FRED B. PARKS, a citizen of the United States,residing at Grand Rapids, in the county of Kent and State of Michigan,have invented certain new and useful Improvements in Tire-Plugs, ofwhich the following is a specification.

My invention relates to improvements in plugs for closing punctures inpneumatic tires; and its object is to provide a plug that will perfectlyadjust itself to a knife-cut or other similar puncture. I attain thisobject by the 7 peculiar construction shown in the. accompanyingdrawings, in which Figure 1 is a perspective of the plug, and Fig. 2shows the same passing through a puncture in a piece of tire.

Similar letters refer to similar parts in both views.

A represents the stem of the plug,which is lenticular in form with theedges sharp, so that they will enter and fill the sharp terminus of aknife-cut. I also make the outer end smaller than the end at the head,so that the plug will enter easily and after having been drawn into thepuncture will expand, so as to fill the puncture and overlap on theoutside, it being understood that the plug is made of very pliablerubbers, so that it may be stretched to several times its normal lengthand will upon resuming its normal size adjust itself to fill everycrevice in a puncture.

' B represents the head of the plug, the form of which is immaterial,and 0 represents a broken section of a tire, showing a puncture 0,through which the plug A is passed.

Having thus fully described my'invention, what I claim as new, anddesire to secure by Letters Patent of the United States, is

1. A tire-plug having a head and a lenticular stem projecting from oneside thereof, said stem thick in the center and tapering to thin sharpedges, substantially as and for the purpose set forth.

2. The combination in a tire-plug of a head and a thin lenticular stemprojecting from one side thereof, said stem tapering smaller toward theend and to sharp edges, substantially as and for the purpose set forth.

Signed at Grand Rapids, Michigan, February 12, 1900.
